区域空气质量数值预报模型

Numerical Regional-Scale Air Quality Forecast Model

给出了区域尺度空气质量数值预报模型的基本物理构架， 重点介绍了欧拉型输送／沉降模式对各种物理 （沉降、输送）、化学 （气相化学与液相化学） 过程、初值与边界条件等问题的处理／简化； 利用本模型作了一周的预报实验， 实验结果与分析说明， 区域空气质量数值预报模型能够较好地反映全国重点城市的空气质量以及污染物随时间的演变态势； 最后， 指出了需要进一步完善的工作。

The paper gives a general description of the numerical regional-scale air quality forecast model, with emphasis on solution schemes for all possible processes (emissions, transport, deposition, chemistry, and initial and boundary conditions) considered in the Eulerian transport/deposition model One-week regional-scale air quality is forecasted using the numerical model Comparison and analysis indicate that the air quality of key cities over China and the time evolution of pollutants over the whole area of China can well be forecasted by the numerical model Further improvements in some important aspects are needed and presented
